Comment 6 Richard W.M. Jones 2012-07-02 11:04:01 EDT
The assertion in comment 5 is in this code:

  int qcow2_cache_destroy(BlockDriverState* bs, Qcow2Cache *c)
  {
    int i;

    for (i = 0; i < c->size; i++) {
        assert(c->entries[i].ref == 0);
        qemu_vfree(c->entries[i].table);
    }

    g_free(c->entries);
    g_free(c);

    return 0;
}

I don't have a value for 'i' but two of the 'entries'
have non-zero 'ref':

(gdb) print *c
$3 = {
  entries = 0x7f22fd8c07b0, 
  depends = 0x0, 
  size = 16, 
  depends_on_flush = false, 
  writethrough = false
}
(gdb) print c->entries[0]
$4 = {
  table = 0x7f22fd8c0a00, 
  offset = 262144, 
  dirty = false, 
  cache_hits = 2964, 
  ref = 1
}
[...]
(gdb) print c->entries[2]
$6 = {
  table = 0x7f22fd8e0e00, 
  offset = 351469568, 
  dirty = false, 
  cache_hits = 33, 
  ref = 1
}

The vcpu is still running, so it's unclear why qemu things its
safe to start destroying the qcow2 cache.
Comment 7 Richard W.M. Jones 2012-07-02 11:33:42 EDT
I don't know if this is definitively the problem, but
these two lines in vl.c look the wrong way round to me:

    main_loop();
    bdrv_close_all();  <<
    pause_all_vcpus(); <<
    net_cleanup();
    res_free();
Comment 8 Richard W.M. Jones 2012-07-03 05:16:30 EDT
Possible duplicates:
bug 798499
bug 798857
bug 805893

I am now able to reproduce this bug almost at will:

$ cd /tmp
$ ulimit -Hc unlimited
$ ulimit -Sc unlimited
$ rm -f test.img
$ qemu-img create -f qcow2 test.img 100M
$ guestfish -a test.img run : part-disk /dev/sda gpt : copy-device-to-device /dev/zero /dev/sda1 size:98M
$ ls
core.23671  test.img

The core file isn't produced every time, but it's produced
pretty often, maybe 1 in 3 runs.  Simply repeat the qemu-img +
guestfish commands until it happens.

To get full debug information about what libguestfs is doing
add the -v and/or -x options to guestfish.  But basically it
appears to happen when we send SIGTERM to qemu.

Comment 10 Richard W.M. Jones 2012-07-04 11:04:03 EDT
The underlying issue is fixed in qemu-kvm >= 1.1.0
which is being rolled out to Fedora Rawhide today.

The workaround mentioned in comment 9 is not required,
and will not go upstream.  The solution is to update
qemu to >= 1.1.0.

Comment 12 Cole Robinson 2012-07-10 09:52:26 EDT
Reopening and moving this bug to F17. If this is a possible data loss issue, we should try and isolate something to backport (rebasing to 1.1 should be a last resort option IMO)
Comment 13 Cole Robinson 2013-04-01 18:16:26 EDT
This should be the fix:

    block: Drain requests in bdrv_close
Comment 14 Cole Robinson 2013-04-02 09:56:56 EDT
Hmm, that wasn't trivial to backport, particularly because some of the plumbing needed for bdrv_drain_all also needs to be backported, and anything non-trivial in this area scares me. Since F17 isn't long for this world, and we haven't seen reports from endusers, just closing this wontfix.
